Stronger effect of temperature on body growth in cool than in warm populations suggests lack of local adaptation

open access: yesEcography, EarlyView.
Body size is a key functional trait that has declined in many biological communities, partly due to changes in individual growth rates in response to climate warming. However, our understanding of growth responses in natural populations is limited by relatively short time series without large temperature contrasts and unknown levels of adaptation to ...

Effect of Glycation Reaction on Volatile Flavor and Gel Properties of Fish Protein Gelatin

open access: yesShipin gongye ke-ji
To improve the flavor of fish protein gelatin, the glycation reaction system was constructed with glucose, and use microplate readers, colorimeters, texture analyzers, rheometers, and gas chromatography-mass spectrometers were used to determine the free ...

Metabolism of cryptoxanthin in freshwater fish [PDF]

open access: yesBritish Journal of Nutrition, 1984
1. In search of other provitamins A, the metabolism of cryptoxanthin was studied in several species of freshwater fish, i.e. Chunna gachua, Labeo boga (retinol-rich) and Heteropneustes fossilis (dehydroretinol-rich). The fish were either allowed to starve for 20–25 d to make their intestines free from carotenoids and vitamin A or kept on a vitamin-A ...

Habitat heterogeneity overrides local processes to drive the species–area relationship of benthic macroinvertebrates in shallow floodplain lakes

open access: yesEcography, EarlyView.
The species–area relationship (SAR) on islands describes how the numbers of species increase with increasing island size (or island‐like habitat, such as lakes). Despite its conceptual importance, there is considerable uncertainty surrounding its shape in freshwater lakes, as well as the potential mechanisms that underlie the SAR.

Production of a diploid hybrid with fast growth performance derived from the distant hybridization of Hypophthalmichthys nobilis (female) × Megalobrama amblycephala (male)

open access: yesReproduction and Breeding, 2022
Based on the distant hybridization derived from Hypophthalmichthys nobilis (bighead carp, BIC, 2n ​= ​48) (♀) ​× ​Megalobrama amblycephala (blunt snout bream, BSB, 2n ​= ​48) (♂), we obtained a novel hybrid (BB) in this study.

Growth response of Heterobranchus longifilis fingerlings fed with varying levels of dietary freshwater mussel (Aspatharia sinuata) [PDF]

open access: yes, 2005
A common bivalve: Freshwater mussel, Aspatharia sinuate was evaluated as a dietary protein supplement in the production diet for Heterobranchus longifilis fingerlings with mean body weight 8.34 plus or minus 10g reared in aquaria tanks.

A test of the abundant‐center hypothesis for stream fishes

open access: yesEcography, EarlyView.
The abundant‐center hypothesis (ACH) provides a conceptual model for predicting range‐wide distributions of species abundance, suggesting that abundance peaks in the center of the geographic range and declines towards range edges. Empirical studies testing the ACH and its subsequent derivations predominantly occurred in terrestrial systems and reported

Freshwater fish functional diversity shows diverse responses to human activities, but consistently declines in the tropics

open access: yesEcography, EarlyView.
Freshwater environments are intertwined with human activities and the consequence has been environmental degradation and biodiversity loss. Fish provide key ecological and economic benefits, and fish abundance and diversity can be affected by human activities resulting in functional diversity (FD) changes that might scale up to ecosystem impacts ...
